NASA Interstellar Voyager probes Get Software Updates From 12 Billion Miles Away

In May 2022, Voyager 1 encountered a challenge as it began transmitting distorted data back to Earth. Engineers at NASA Jet Propulsion Laboratory (JPL) identified the issue as a software glitch in the probe attitude articulation and control system (AACS), responsible for maintaining the proper alignment of the probe antenna with Earth.

Responding to this anomaly, JPL engineers devised a software patch to rectify the glitch. The corrective patch was initiated in October 2022 and took 18 hours to traverse the vast distance to Voyager 1, successfully completing installation on November 18, 2022. Consequently, Voyager 1 has resumed normal data transmission.

Beyond addressing the software glitch on Voyager 1, JPL engineers are actively developing additional software updates. These updates aim to prevent the accumulation of debris in the thrusters of both Voyager probes and are scheduled for transmission in early 2024.

The successful installation of a software update for NASA Voyager 2 probe marked another achievement, occurring on October 25, 2023. The update, transmitted from Earth on October 20, 2023, also required 18 hours to reach Voyager 2, ensuring the probe continued operational success.

The capability to send software updates over a distance of more than 12 billion miles to the Voyager probes underscores the ingenuity of NASA engineers. It further emphasizes the enduring functionality of the Voyager probes, which have surpassed 46 years in service.

As the farthest human-made objects from Earth, Voyager 1 currently explores interstellar space, while Voyager 2 is anticipated to reach interstellar space in 2025. Both probes persist in delivering valuable scientific data, enhancing our understanding of the outer solar system and interstellar space.

The recent software updates, transmitted from Earth to the Voyager probes through the Deep Space Network—an intricate system of global radio antennas dedicated to communicating with NASA deep space probes—attest to the resourcefulness and commitment of NASA engineers. This achievement not only demonstrates the successful resolution of technical challenges but also highlights the ongoing potential for communication with spacecraft, even when situated billions of miles away.

The Voyager probes, as humanity most distant technological emissaries, continue to enrich our knowledge of interstellar space and are anticipated to remain operational for several more years, providing an unprecedented perspective into the depths of our cosmic surroundings.
